Check out this pop-locking biker busting moves during a stop at a red light.

Hilarious video shows the man wearing a backpack and a helmet popping, locking and dropping shapes as he waits in a line of cars. He shows no sign of stopping as other motorists stop and stare at his bizarre antics.

It's not clear whether he was listening to a song via some headphones. But what is clear is that he was keen to showcase his routine at every available opportunity.

Motorists in a car behind filmed the astonishing scene on a cell phone.
